[S] graphic options in Splus

I have a couple of questions regarding advanced graphic commands.

I have a series of regression plots with 2 lines and one set of
points, for a total of 3 graphic objects for each graph. I'd
like to use the legend option, to explain what each object represents.
I have used this successfully for both lines on the graph, but
when I try to include the points in the same call to legend, I get
an error message.

Secondly, can I make a direct call to the lm.objects($coefficients,
$R2, $P.value) to define the legend text statements?

If anyone can suggest a way to do this I certainly like to know
how to proceed.

Thanks for the ideas
